My invention relates to locomotive axles having side play, and more particularly to a connecting rod connection in combination with such axles. Itis an object of my inven- .5 tion to so design the said connection that it may be applied to a driving axle of a locomotive. l s To this end, I anchor the big end of the connecting rod against lateral play on the cou ling rod while the pin is free to slide in the ig end.

, It has already been dpro osed to provide side play for the couple ax es of locomotives within andwithout the fixed wheel base but l5 obviously this vis not a perfectly satisfactory solution of the problem as the fixed axles will not adapt themselves to curves. This drawback is overcome in my invention by providin means permitting not only cou led, but a so driving axles to be equippe for side play. o

For any axle having side play the coupling rods must be so stiil' as not to yield appreciably to lateral forces and it is obvious that 5 in the present instance the same condition must be fulfilled. I.

In the accompanying drawing a pin o f a driving Wheel and parts of the connectin and coupling rods are illustrated by way o example. Y

In the drawing Fig. -1 is a transverse section through the bush of the coupling rod,

Fig. 2 is a plan view, partly in section on the axis of the pin.

Fig. 3 is a plan view of a complete axle and wheels.

Referring now to the' drawing, a is a con- 40 necting rod having the usual pin b to `enable the rod to yield to the movements of the springs, c is a bushing in the coupling rod, d

is the crank pin, which is secured in a wheel p in the usual manner, p, p being the wheels, and g being the axle, e is a ange at the inner end of the bushing c, said bushing extending into the connecting rod big end g,

f is a washer inserted between the coupling rod a and the big end g, 1' is a nut secured on the outer end of the bushing c by a thread o,

canon, and in Germany :ahw-y i2. 192s.

l: is washer on the end Ouh@ pin g, and z l is a nut for holding the washer k.

m is fork formed on one of the coupling rod parts to surround the eye of the other part which is held on the pin b, and n are stays in the fork arranged so far apart as not to interfere withthe play of the parts.

The Washer f is fixed on the bushing c so that the eye of the coupling rod a and the big end g are held on the bushing against axial displacement and so the big` end g is anchored to the couplin rod a but the pin d is free to slide in the bus ing 0 as the pin is longer than the bushing. The sliding movement is limited by the washer k on the outer end of the pin d.

It-will be understood that the side play of the4 drivincr axle is not interfered with by the rods while on the other hand the big end is held in line with the axis of the cylinder y being anchored'on the coupling rod a.

I claim: f

l. The combination of a crank pin, a main connecting rod, a side connecting rod, and means'for mounting said rods on said crank pin for axial movement relative thereto, said means consisting of a sleeve slidably mounted on said crank pin and carrying said rods, a iange on one end of said sleeve for preventing movement of said rods in one direction, means l for spacing said rods longitudinally on said sleeve, and means on said sleeve for preventing movement of said rods in the opposite direction.

2. The combination of a crank pin, a main connecting rod, aside connecting rod, andy means for mounting said rods on said crank pin for axial movement relative thereto, said means consisting of a sleeve slidably mounted on said crank pin andcarryin said rods,

a flange on one end of said sleeve or reventl ing movement of said rods in one direction, and'means on said sleeve for preventing movement of saidrods in the opposite direction.
